Veto

Executive rejection of a legislative proposal or joint resolution submitted for legal approval. Should an executive reject a measure, it can attain legal status only if the House and Senate individually vote (by a two-thirds majority) to overturn the rejection. An alternative type of executive rejection – an indirect rejection – happens if the legislature has concluded its session and cannot reconvene, and the executive fails to approve the legislative proposal within the mandated ten-day timeframe (excluding Sundays).
